In this study, author developed a method of determining tetramethylammonium hydroxide and tetramethylammonium salts, present in industrial wastewater as tetramethylammonium ions (TMA), by liquid chromatog.-tandem mass spectrometry (LC-MS/MS). Tetramethylammonium hydroxide was used as a standard solution The lower limit of quantification for TMA anal. by solid-phase extraction (SPE) using a weak cation exchange resin (Oasis WCX) was 0.00034 mg L-1, and the recovery of surrogate standards ranged from 50 to 120%. Author investigated 30 industrial wastewater samples from Fukuoka Prefecture by the developed TMA anal. method. TMA was detected in two samples, H and X, with concentrations of 0.0014 and 2.5 mg L-1, resp. In sample X, the immobilization of Daphnia magna was observed even at 50% dilution, and the 48 h-EC50 was 62%. The toxicity removal test indicated reduced toxicity for sample X after SPE-WCX. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Product Details of 75-57-0).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Product Details of 75-57-0
